Ah! Yes, I have found the one on the Heritage Steam Supplies website.... I bet it's a 2" one, however, I will email them and see what it is exactly, and ask if a larger one can be ordered........

Cheeeeers! :D

Yoh could soon cut two of the plastic ones. Then glue together

I bought mine from the Manzell supplier near Southampton (?).

It's not, no... I contacted them and the only one they supply is 2" long with a 1 1/4" pitch mounting hole....

So on with the search! :)

It was Colin Hatch who, at that time, was the NTET spares person who put me in touch with the UK supplier. You may like to contact whoever does this now for the NTET.
